My primary and secondary air was at 120 after 2 weeks sitting. The aux was at zero.
Started bus to wash. After2 hours pri and sec brake were zero pressure. Aux was at zero.
Cranked bus and built pressure until air dryer exhusted. Pulled into building and watched pressures. The Aux dropped 10 pounds in one quick moment. pressures held for about 5 minutes and droped 10lbs, pressure held for 2 to 3 minutes and droped 10 more lbs, 3 minutes later it dropped 10 lbs and held, 3 minutes later it dropped 10 lbs and held for 4 minutes, i quite tracking then.
